Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of many light efficiencies LED Down lamp, simple in structure, good heat dissipation effect, and long service life, does not need mounted lens just can improve the optically focused effect of Down lamp.
The technical solution of the utility model is as follows: a kind of many light efficiencies LED Down lamp, comprise shell and light source board, light source board is fixing in the enclosure, the aluminium cup that also comprises translucent cover plate and cover plate below, cover plate and aluminium cup are installed on the bottom in outer thimble, aluminium cup is fixed by screw and described shell, offers porosely at the middle part of described cover plate, and the diameter in hole or the length of side are the 1/4-1/3 of cover plate diameter; On the periphery wall of described shell, be provided with fin, fin is upwards extending longitudinally at the periphery wall of shell, and fin arrives after outer casing top surface again the radially extension along outer casing top surface.
Further, described hole is circular hole, and the surrounding in hole also offers bar-shaped trough, and bar-shaped trough points to the center of circular hole.
Further, described aluminium cup comprises loop portions, and the upper and lower end of loop portions is respectively arranged with flange, and screw is connected with described loop portions through after shell, and aluminium cup and shell are fixed; Described cover plate is placed in aluminium cup upper end flange.
Further, also comprise power supply, described power supply is connected with power line by inserting terminal, and power line passes heat-shrinkable T bush and is connected with light source board after shell.
Further, described light source board is PCB light source board, and described light source board is fixed by screw and shell.
Further, described shell is tubular, and the bottom of shell is provided with the flange that turns up, and described fin is evenly arranged.
The utility model arranges at the middle part of cover plate the hole that ventilation and heat is used, the bottom of Down lamp is not closed, hot-air can be dispersed by hole from lamp cylinder introversion, bottom at Down lamp also increases radiator structure, be combined with common heat radiation with fin, and fin is also arranged in the top of shell, has increased area of dissipation, these have all improved the service life of radiating effect and light fixture; And the hole of heat transmission and groove, light can not filtered and stop by cover plate from middle part directly through cover plate, and the circumference of translucent cover plate stops that a part of light source is through also carry out the diffusion of part light source simultaneously, light arrives on annular aluminium cup and is reflected again, improves light emission rate.Cover plate is realized middle part optically focused simultaneously, and light diffusion and heat sinking function, do not need to carry out optically focused with lens, just can obtain the optically focused of suitable intensity, reduced light fixture cost, makes Down lamp light efficiency have diversity.
By technique scheme, the beneficial effects of the utility model are: LED cylinder lamp structure is simple, good heat dissipation effect, long service life, the optically focused effect that does not need mounted lens just can improve Down lamp has realized the diversified function of light under condition cheaply, and Down lamp light efficiency has diversity.
