Description
Technical field
This utility model relates to a kind of Down lamp, particularly relates to a kind of cylindrical ceiling lamp.
Background technology
In order to improve the service behaviour of Down lamp and extend the working life of Down lamp, it usually needs to Down lamp design heat radiation knot
Structure, traditional heat dissipating method is that light source board is arranged on housing bottom surface, utilizes the housing (namely bonnet) of Down lamp right as far as possible
The heat of light source board distributes, and later, has people to increase air-flow through hole on the housing (namely bonnet) of Down lamp thus accelerates
The diffusion of the internal steam of Down lamp, can further improve the radiating rate of Down lamp.
But, some place, country to fill anti-Pyroxylin, and require Down lamp housing in having regulation floor now
The surface temperature of (namely bonnet) must not exceed 80 degree.When actual installation uses, the fire prevention bale of cotton in floor is lived
Down lamp housing can greatly reduce the thermal convection current at Down lamp rear portion, and Down lamp housing outer surface temperature remains high, and also cannot meet phase
Close regulation, there is certain potential safety hazard.
Utility model content
This utility model provides a kind of Down lamp, which overcomes the deficiency existing for background technology.This utility model solves
Its technical problem be the technical scheme is that
A kind of Down lamp, including bonnet, front ring, light-passing board, light source board, power supply apparatus, described bonnet is the shell of bottom surface opening
Body structure, the middle part of described front ring is provided with through hole, and described light-passing board is arranged in the middle of the through hole of described front ring, and described front ring covers
The opening of described bonnet forms assembly room, in described light source board and power supply apparatus are arranged on described assembly room and electrically connect, including
Being positioned at the support member of assembly room, described support member is connected with described front ring, described support member and the sidewall of described bonnet and upper
End face is every sky, and described light source board is arranged on support member, described light source board near described front ring arrange and not with described bonnet
Contact, the heat of described light source board can pass to front ring by support member and be distributed to air by front ring.
The technical program is compared with background technology, and it has the advantage that
Light source board is arranged near front ring, and support member does not contacts with the sidewall of bonnet and upper end face with light source board, light source board
Heat is dispersed in the middle of air by support member and front ring, at utmost prevents the heat of light source board to be delivered on bonnet, effectively
Ground controls the temperature of bonnet, prevents bonnet temperature too high, improves the safety used under anti-Pyroxylin environment.

Detailed description of the invention
Refer to Fig. 1 to Fig. 4, a kind of Down lamp of the present utility model, including bonnet 10, front ring 20, light-passing board 30, light source board
40, power supply apparatus 50.Described bonnet 10 is the shell structure of bottom surface opening, including sidewall 12 and upper end face 14.Described front ring 20
Middle part be provided with through hole 22, described light-passing board 30 is arranged in the middle of the through hole 22 of described front ring.Described front ring 20 cover described after
The opening of lid 10 forms assembly room 60.In described light source board 40 and power supply apparatus 50 are arranged on described assembly room 60 and electrically connect.
Down lamp also includes the support member 70 being positioned at assembly room 60, and described support member 70 is connected with described front ring 20, described support member 70
With the sidewall 12 of described bonnet and upper end face 14 every sky.Described light source board 40 is arranged on support member 70, and described light source board 40 leans on
Nearly described front ring 20 arranges and does not contacts with described bonnet 10, and the heat of described light source board 40 can be passed to by support member 70
Front ring 20 is also distributed to air by front ring 20.
Owing to light source board 40 is arranged near light-passing board 30, light source board 40 does not contacts with bonnet 10, and support member 70 is not the most with rear
The sidewall 12 of lid 10 contacts with upper end face 14, and i.e. support member 70, light source board 40 and the sidewall 12 of bonnet 10 and upper end face 14 are every sky,
And light source board 40 passes through front ring 20 and light-passing board 30 away from the upper end face 14 of bonnet 10, light source board 40, the heat of support member 70
Distribute to air, therefore can farthest prevent light source board 40, the heat of support member 70 from passing to the sidewall 12 of bonnet 10
With upper end face 14, thus reduce sidewall 12 and the temperature of upper end face 14 of bonnet 10.
Preferably, described front ring 20 is provided with the locating ring 24 extending in described bonnet 10 opening, and described locating ring 24 encloses
Described through hole 22, the upper surface of described locating ring 24 is become to be provided with slot 26.Described support member 70 includes base plate 72 and is connected to the end
The surrounding edge 74 of edges of boards edge.Described light source board 40 is connected to the lower surface of described base plate 72, and described surrounding edge 74 is inserted into described slot
In the middle of 26.The heat of light source board 40 is delivered to locating ring 24 by support member 70, and the inside and outside circle side face of slot 26 can be effectively
Dispelling the heat, therefore, slot 23 is the bigger the better with the contact area of surrounding edge 74.
Preferably, the material of described support member 70 is aluminium alloy.So, support member 70 heat conductivity is the best, itself
It it is exactly a heat dissipation element.
Preferably, described light-passing board 30 inside contracts and is arranged in the middle of described through hole 22, described light-passing board 30 and described locating ring
The inner surface of 24 is connected together.Spacing H is there is between described light-passing board 30 and the lower surface of described front ring 20.Spacing H is the biggest,
Dispel the heat the fastest.
