303, described substrate 400 depression arranges fixing groove 401, and described fixing post 303 is arranged in described fixing groove 401
In 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, such as Fig. 6
Shown in, described lamp housing 200 offers some air vents 206.So, the hot-air in lamp housing 200 can lead to
Cross air vent 206 and be circulated to outside, and the relatively low air of external temperature also can pass into lamp housing 200, such as,
Described air vent 206 is opened on described shell wall 202, and such as, some described through holes are uniformly opened in described
On shell wall 202, so, heat can pass through lamp plate 500 to major part, substrate 400 is transferred to radiating seat 300
And then be transferred to lamp housing 200, lamp housing 200 distribute, and fraction heat can be circulated by air and be carried
Walk, thus be effectively increased radiating efficiency, it is to avoid heat is assembled in lamp housing 200 and cannot be distributed rapidly.
Such as, described air vent 206 is circular, and and for example, described air vent 206 is square, and for example, and institute
Stating air vent 206 is polygon, and 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 by lamp housing 200
Interior is gradually increased, and such as, described air vent 206 has hole wall, and such as, described hole wall tilts
Arranging, such as, described hole wall is internal outside gradually to outer inclination, so to lamp housing 200 by lamp housing 200
The aperture making air vent 206 is gradually increased, beneficially the discharge of hot-air, such as, and described hole wall both sides
The different setting of slope tilted, i.e. hole wall is different at the slope of both sides, so so that circulate along hole wall
Air velocity differ, owing to the density of hot-air is less, and cold air density is relatively big, and so, heat is empty
Gas circulates concentrating to the side of hole wall, and cold air circulates concentrating to the opposite side of hole wall, and due to hole
The slope of wall differs, and then makes the velocity of liquid assets of hot-air and cold air inconsistent, and then makes air
Exchange velocity is accelerated so that heat exchanger effectiveness improves.
In the present embodiment, as shown in Figure 4 and Figure 5, it is inserted directly into power supply terminal due to electrical terminals 510
410, so that without connecting electrical equipment by cable in display lamp 10, effectively reduce owing to cable accounts for
Volume, add the clearance spaces in lamp housing 200, and then make better heat-radiation effect, and be conducive to
The assembling of display lamp 10.Although being directly connected to of electrical terminals 510 and power supply terminal 410 can save space,
But owing to the electric current between lamp plate 500 and substrate 400 is all passed by electrical terminals 510 and power supply terminal 410
Defeated, easily make heat concentrate on electrical terminals 510 and power supply terminal 410, in order to avoid electrical terminals
510 and the power supply terminal 410 overheated generation short circuit due to conduction, in one embodiment, as shown in Figure 4,
Present invention additionally comprises heat radiation lasso 700, described heat radiation lasso 700 is sheathed on outside described electrical terminals 510,
