In order to fix substrate 400 and lamp plate 500, such as, described radiating seat 300 inwall projection arranges at least two step
Portion, described substrate 400 and described lamp plate 500 be connected to described stage portion successively, such as, as it is shown in figure 5, described radiating seat 300
Internal projection arranges first step portion 301 and second step portion 302, and such as, described substrate 400 is disposed in proximity to described radiating seat
The first step portion 301 of the one end bottom 300, described lamp plate 500 is disposed in proximity to second of described radiating seat 300 opening part
Rank portion 302, the thickness in described first step portion 301 is more than the thickness in described second step portion 302, so, substrate 400 and lamp plate
500 can be fixed in described radiating seat 300 well.Such as, the inwall projection of described radiating seat 300 arranges fixing post
303, described substrate 400 depression arranges fixing groove 401, and described fixing post 303 is arranged in described fixing groove 401 so that substrate
400 can be fixed in radiating seat 300 by fixing post.
Assemble in lamp housing 200 in order to avoid heat and cannot distribute rapidly, in one embodiment, as shown in Figure 6, institute
State lamp housing 200 and offer some air vents 206.So, outside the hot-air in lamp housing 200 can be circulated to by air vent 206
Portion, and the relatively low air of external temperature also can pass into lamp housing 200, such as, described air vent 206 is opened in described shell wall
On 202, such as, some described through holes are uniformly opened on described shell wall 202, and so, major part heat can pass through lamp plate
500, substrate 400 is transferred to radiating seat 300 and then is transferred to lamp housing 200, lamp housing 200 distribute, and fraction heat can lead to
Cross air circulation and be pulled away, thus be effectively increased radiating efficiency, it is to avoid heat is assembled in lamp housing 200 and cannot be dissipated rapidly
Send out.
Such as, described air vent 206 is circular, and and for example, described air vent 206 is square, and for example, and described air vent 206
For polygon, such as, described polygon includes hexagon, octagon.
In order to improve the drafting efficiency of lamp housing 200 further, the width of described air vent 206 is internal outwards by lamp housing 200
Portion is gradually increased, and such as, described air vent 206 has hole wall, and such as, described hole wall is obliquely installed, and such as, described hole wall is by lamp
Shell 200 inside gradually to outer inclination, so makes the aperture of air vent 206 be gradually increased to lamp housing 200 outside, is conducive to heat
The discharge of air, such as, the different setting of slope that described hole wall both sides tilt, i.e. hole wall is different at the slope of both sides, so,
Air velocity along hole wall circulation is differed, and owing to the density of hot-air is less, and cold air density is relatively big, so,
Hot-air circulates concentrating to the side of hole wall, and cold air circulates concentrating to the opposite side of hole wall, and oblique due to hole wall
Rate differs, and then makes the velocity of liquid assets of hot-air and cold air inconsistent, and then air exchange speed is accelerated so that
Heat exchanger effectiveness improves.
In the present embodiment, as shown in Figure 4 and Figure 5, owing to electrical terminals 510 is inserted directly into power supply terminal 410, so that
In obtaining street lamp 10, nothing connects electrical equipment by cable, effectively reduces the volume taken due to cable, adds in lamp housing 200
Clearance spaces, and then make better heat-radiation effect, and the assembling of beneficially street lamp 10.Although electrical terminals 510 and feeder ear
Son 410 be directly connected to save space, but due to the electric current between lamp plate 500 and substrate 400 all by electrical terminals 510
Transmit with power supply terminal 410, easily make heat concentrate on electrical terminals 510 and power supply terminal 410, in order to avoid power connection end
Son 510 and power supply terminal 410 overheated generation short circuit due to conduction, in one embodiment, as shown in Figure 4, the present invention also wraps
Including heat radiation lasso 700, described heat radiation lasso 700 is sheathed on outside described electrical terminals 510, and the two of described heat radiation lasso 700
End abuts with described electrical terminals 510 and described power supply terminal 410 respectively.By heat radiation lasso 700, electrical terminals 510 is wrapped
Cover so that the heat of electrical terminals 510 and power supply terminal 410 can be absorbed by heat radiation lasso 700, and by heat radiation lasso
